JOHN C. EGLY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY DIRECT ANDMESNE ASSIGNMENTS, TO THOMAS A. PEARCE AND ROSE E. EGLY,

OF SAME PLACE.

CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 420,190, dated January28, 1890.

Application filed June l0, 1889. Serial No. 313,742. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN C. EGLY, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Circular-KnittingMachines,

which improvement is fully set forth in the following specification andthe accompanying drawings.

My invention relates to Vimprovements in knitting-machines; and itconsists in so constructing the cams thereof that as they wear off theymay be adjusted, and thus preserve their proper distances with relationto the adjacent parts of the machine.

Figure l represents a top or plan View, partly broken away, of theportion of a knitting-machine embodying my invention. Figs. 2 and 3represent vertical sections in opposite directions on line fr 5v, Fig.l. Fig. 4 represents a view of a modification.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the cam cylinder of aknittingmachine, which, excepting the features of my invention appliedthereto, is constructed and adapted to operate in a well-known manner.

B designates the usual cams, which are at the ends of the band or ringC.

In knitting-machines as heretofore constructed the band or ring whichhas the cams at the ends thereof is made of a single piece of metalsecured to the inner face of the cylinder A, whereby when said cams wearoi the band is removed as comparatively My invention is designed toremedy this, and to this end I form the band in sectionsor segments,which are adjustably connected with the cylinder by means of screws D,which are secured to the sections and pass through horizontal slots E inthe cylinder A. By this provision the cams B may be set nearer to eachother when their faces wear o, the screws D being previously loosenedand duly tightened when the adjustment is accomplished. In order topreserve t-he continuity of the upper edge of the band C at theseparated ends of the sections of the same, and thus avoid a space intowhich the needles may drop, there is formed on the end of one section ahorizontallyextending tongue F, which enters a groove or slot G in theend of the other section, as will be most clearly seen in Fig. 2, itbeing noticed that the upper edge of the tongue is continuous of theupper edge of the section of the band with which it is connected, andthe end of the upper edge of the other section joins the upper edge ofthe tongue, so that as the sections are mowed to adjust the cams thetongue plays in the groove or slot Gr, and thus there is practically nobreak in the upper edge of the band, and the space between the sectionis covered or guarded by the tongue, the latter spanning. said space, asis evident.

In Fig. 4 the portion of the band containing the cam is shown asadjustably connected with the adjacent portion of the band, saidportions being also provided with a tongue and groove, so that as thecam portion is adjusted the existing space between the same and the bandis covered and guarded similar to that shown in Fig. 2.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

l. A cylinder, in combination with a band having a cam on the endthereof adj ustably connected with the said cylinder, whereby said cammay be adjusted, substantially as Y described.

2. A cylinder, in combination with a camcarrying band formed in sectionswhich are adjustably connected with the said cylinder, whereby the camsmay be adjusted, substantially as described.

3. A cylinder, in combination with a camcarrying band formed in sectionswhich are adj ustably connected with the said cylinder, and providedwith means for closing the s space between said sections, and preservethe continuity of the edge of the band, substantially as described.

4. A cylinder, in combination with a camcarrying band formed insections, one of which has a groove or` nslot and the other a tongue,the latter being continuous of the Vedges of the sections, substantiallyas and for roo the purpose set forth.

JOHN C. EGLY.
